New Members phillipdmatthews Posted May 16, 2019 New Members Share Posted May 16, 2019 (edited) Hello to Everyone... I'm hoping that someone might be able to advise me about preventing oxidation on a pyritized ammonite. I have no doubt that this question has cropped up before and wondered of anyone had some good advice. I'm reluctant to immerse it in acetone (Seems a tad aggressive?) I know that polishing it will only be a temporary fix. So... Two questions - what can I use to polish it back to a shiny finish and... Two... I do have some clear, low viscosity, pure silicon oil - I use it to fill vintage compasses that I restore. Does anyone know if this would react with the FeS2 in an adverse way? Sadly my knowledge of chemistry is very lacking. :-( I'd love to hear your thoughts...
